Hexavalent Chromium Hexavalent Chromium - Cr(VI) Hazard Overview Solutions Regulations Learn More Hazard Overview What is hexavalent chromium? Hexavalent chromium is one of several oxidation states of the element chromium and is commonly used in chrome plating operations to deposit a corrosion-resistant coating on metal parts. Hexavalent chromium is also produced when chrome metal or alloys containing chrome metal are heated to high temperatures, such as during the welding of stainless steel. What are the hazards associated with hexavalent chromium? Cr(VI) is known to cause cancer. In addition, it targets the respiratory system, kidneys, liver, skin and eyes. Is there a special emphasis program associated with this topic? Occupational exposure to hexavalent chromium falls within the OSH Division health hazards special emphasis program. Solutions What can I do to protect myself? Employees working around chrome plating operations should ensure they are wearing the necessary personal protective equipment when working around these processes. Employees who are welding stainless steel and other high chromium content alloys should be sure to position the workpieces between themselves and the exhaust ventilation. Your employer is required to provide respiratory protection in accordance with the respiratory protection standard, 29 CFR 1910.134, when ventilation is not sufficient to maintain your exposure below the permissible exposure limit. What resources are available to assist employers? Training and Outreach Services Related presentations on welding and cutting for workplaces in general industry and construction, toxic and hazardous substances, respiratory protection, and hazard communication are available to assist employers to train their staff. The presentations should be modified to address site-specific conditions and hazards. In addition, the education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request. Further, the following pre-recorded webinars can also be used to assist with employee training: hazard communication, health hazards: special emphasis programs, and respiratory protection. Lastly, the NCDOL Library offers free safety and health videos (including streaming video services) and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC). Safety and Health Programs Example programs for hazard communication, hazardous chemicals and respiratory protection can be used to assist employers in the development of their overall comprehensive safety and health program. A PPE hazard assessment should be used to ensure that all PPE has been identified to protect the employee from exposure. A-Z Safety and Health Topics Additional resources can be found on the A-Z topics pages for respiratory protection, hazard communication, eyewash stations and emergency showers and personal protective equipment. Consultation Services Lastly, the consultative services bureau provides free and confidential onsite consultation regarding worksite safety and health hazards. Regulations Which standards apply? OSH has adopted the following standards which are applicable to hexavalent chromium in North Carolina.
